Enterprise Value Explained: Market Cap, Debt, Cash, and EV/EBITDA

Market cap vs. enterprise value

Market capitalization is the share price times shares outstanding — the value of the stock alone. It is quick and useful, and it is how companies get sorted into large-, mid-, and small-cap buckets. What it ignores is the company's debt and cash.

Consider two companies that each have a $10 billion market cap:

• Company A carries $2 billion of debt and holds $1 billion of cash → EV = $10B + $2B − $1B = $11 billion.
• Company B has no debt and holds $3 billion of cash → EV = $10B + $0 − $3B = $7 billion.

Same market cap, very different real price tags. A debt-heavy company has an EV above its market cap; a cash-rich company can have an EV below it. That gap is the whole reason EV exists.

Why debt is added and cash is subtracted

Think like an acquirer buying the entire business:

• Add debt, because a buyer inherits the company's debts and must pay or assume them. That is a real part of the price.
• Subtract cash, because the buyer also gets the company's cash, which effectively offsets the purchase price.

This is the conventional definition used across finance, not an official regulatory formula, and the debt and cash figures come from the balance sheet (reported in a company's Form 10-K), so they are point-in-time snapshots.

A worked example

Take Company A above: a $10 billion market cap, $2 billion of debt, and $1 billion of cash. Its enterprise value is 10 + 2 − 1 = $11 billion.

EV/EBITDA basics

EV is most often used in a ratio called EV/EBITDA. EBITDA stands for earnings before interest, taxes, depreciation, and amortization — a rough proxy for the cash a company's core operations generate before financing and accounting choices.

Dividing EV by EBITDA gives a valuation multiple. Example: an $11 billion EV ÷ $1 billion of EBITDA = an EV/EBITDA of 11. Its main advantage over the P/E ratio is that it looks at the value of the whole firm against the firm's operating cash generation, so it allows comparisons across companies with very different levels of debt — companies you could not fairly compare on P/E alone. It can also be computed for firms reporting a net loss, since EBITDA is usually still positive.

The limits

EV is more complete, not perfect:

• EBITDA is not cash flow. It leaves out real costs the business genuinely must pay — capital spending and interest. A common critique of EBITDA is precisely that it flatters a business by ignoring those bills. For a stricter cash measure, investors look at free-cash-flow-based yields.
• Debt and cash figures are snapshots. They come from a balance sheet on one date and can shift quickly.
• Definitions vary. More complete formulations add items like preferred stock and minority interest, so two published EV figures for the same company may differ.
• EV is an input, not a verdict. Neither market cap nor EV tells you whether a stock is a good investment; both are comparison tools, best used alongside earnings, growth, and cash flow.
